The starting materials for the preparation of the novel compounds of formula I are 2,6-dihydroxypyridine derivatives of the formula: ##SPC3##

wherein X and Y have the above-stated meaning. These starting compounds may be prepared in a known manner analogous to the method described by Bobbitt and Scola, Journ. of Org. Chem. 25, 560, by the condensation of correspondingly substituted acetic acid amides with correspondingly substituted β-ketocarboxylic acid esters. They may also be prepared in accordance with various other processes, as described for example in the monograph "Heterocyclic Compounds Pyridine and its Derivatives Part. 3" by Klingsberg. This monograph has appeared in the frame of the series published by Arnold Weissberger "The Chemistry of Heterocyclic Components", Interscience Publishers. The 2,6-dihydroxypyridine derivatives of formula II, according to Bobbitt and Scola, ibid., are converted by means of phosphoroxychloride or analogously by means of phosphoroxybromide at 180°C. into the corresponding 2,6-dichloro or 2,6-dibromopyridine derivatives of formula III: ##SPC4## wherein X and Y have the above-stated meanings and Hal is bromine or preferably chlorine.

For the preparation of compounds of formula I, wherein Z₂ stands for chlorine or bromine and to which formula Ia then pertains, a compound of formula III is reacted with a compound of formula IV in accordance with the reaction: ##SPC5##

Q in this instance is hydrogen or a metal, preferably an alkali metal such as sodium or potassium. In the event that Z₁ stands for --SO₂ R₁₂, zinc is especially preferred.

Reaction (1) is carried out in equimolar ratio at temperatures of 20°-100°C. in a suitable inert solvent. The exchange of the chlorine or bromine atom in the 6-position is ascertained by analysis of the NMR absorption of the obtained compound of formula Ia.

To the extent that in formula IV, Z₁ stands for the radicals: ##EQU14## --NH--OR₁₀ or ##EQU15## hydrogen is appropriately selected for Q, i.e., in the reaction equation (1) formula IV then stands for the compounds ##EQU16## H₂ NOR₁₀ or ##EQU17## In this instance, the reaction is carried out in accordance with reaction equation (1), preferably in the temperature range of 20° to 50°C. and as suitable inert solvents, alkanols with a chain length of 1 to 4 carbon atoms are preferably used. In those instances where the physical properties are appropriate, an excess of one of the reaction constituents may also serve as the solvent.

To the extent that in formula IV, Z₁ stands for cyano or for --SO₂ R₁₂, a metal is appropriately selected for Q. preferably an alkali metal such as sodium or potassium and in the event that Z₁ is SO₂ R₁₂, zinc is particularly preferred. In reaction equation (1), formula IV then stands for the compounds NaCN, KCN and Zn(SO₂ R₁₂)₂. In this instance, the reaction in accordance with reaction equation (1) is carried out preferably in the temperature range of 60°-80°C. in a suitable organic solvent such as an alcohol, ether, ester, carboxylic acid amide, N-substituted carboxylic acid amide such as dimethylformamide, dialkylsulfoxide such as dimethylsulfoxide or dialkylsulfone, all of these preferably having not more than 6 carbon atoms. In the reaction of sulfinates, the addition of a copper-I-salt is advantageous.

To the extent that in formula IV, Z₁ stands for the radicals --OR₁₂ or --SR₁₂, a metal atom is selected for Q, preferably an alkali metal atom such as sodium or potassium. In reaction equation (1), formula IV then stands for the compounds NaOR₁₂, NaSR₁₂, KOR₁₂ and KSR₁₂. In this instance, the reaction is conducted in accordance with reaction equation (1), preferably in the temperature range of 60°-100°C., in an inert organic solvent, e.g., an aromatic hydrocarbon such as benzene, toluene or xylene, or in an excess of the reaction constituent HOR₁₂ or HSR₁₂ as the solvent.

The compounds of formula Ia may be further reacted in accordance with the reaction: ##SPC6##

This reaction is carried out at temperatures of 20°-200°C. in a suitable solvent. The molar ratio of reactants is 1:1.

When Z₂ is OH in the compound of formula V, there is used a suitable alkali metal hydroxide such as sodium hydroxide or potassium hydroxide in an aqueous or aqueous-alcoholic medium. However, sodium carbonate, potassium hydroxide or similar compounds which release hydroxyl ions in an aqueous medium may also be used. The solvents may be alkanols having 1 to 4 carbon atoms. The preferred temperature range is 70°-150°C.

If Z₂ is --SH in the compound of formula V, an alkali metal hydrosulfide, preferably NaSH or KSH, is used and the reaction is carried out in an aqueous medium, preferably at temperatures of 100°-150°C.

In the event Z₂ stands for --OR₁₂ or --SR₁₂, an alkali metal, preferably sodium or potassium, is selected for Q in formula V and the reaction constituents are reacted at temperatures of α°-150°C., preferably at 60°-100°C., in a suitable inert solvent, e.g., an aromatic hydrocarbon such as benzene, toluene or xylene, or in an excess of the reaction constituent HOR₁₂ or HSR₁₂ as solvent.

In the event Z₂ is cyano or --SO₂ R₁₂ in formula V, a metal is selected for Q, preferably an alkali metal such as sodium or potassium or when Z₂ is --SO₂ R₁₂, zinc is also useful. The reaction between these compounds of formulae Ia and V is carried out in a suitable organic solvent at temperatures of 20-100°C. and preferably 60°-80°C. Suitable organic solvents, for example, include alcohols, ethers, esters, carboxylic acid amides, N-substituted carboxylic acid amides such as dimethylformamide, dialkylsulfoxides such as dimethylsulfoxide or dialkyl-sulfones, all having preferably not more than 6 carbon atoms. In the use of sulfinates, the addition of copper-I-salt is advantageous.

In the event Z₂ is ##EQU18## --NH--OR₁₀ or ##EQU19## in formula V, hydrogen is selected for Q, and the constituents are reacted at 100°-200°C., preferably at 160°-180°C. in an inert solvent, preferably an alkanol having 1 to 4 carbon atoms or, in those instances where the physical properties are appropriate, an excess of one of the reaction constituents may be used as the solvent.

Novel compounds wherein Z₂ has the same meaning as Z₁ may be prepared in accordance with the reaction: ##SPC7##

wherein a compound of formula III is reacted with a compound of formula IV in a molar ratio of at least 1:2 in a suitable solvent at temperatures of 20° to 200°C. When Z₁ is ##EQU20## --NH--OR₁₀ or ##EQU21## in formula IV, hydrogen is selected for Q, and when Z₁ is --CN, --OR₁₂, --SR₁₂ or --SO₂ R₁₂, a metal is selected for Q, preferably an alkali metal such as sodium or potassium. Also when Z₁ is --SO₂ R₁₂, zinc is suitable. Suitable solvents are alcohols, ethers, hydrocarbons, etc. The selection of the solvent may be the same as described for reaction (1).

Novel compounds when Z₂ is --OH may also be prepared by the reaction of a 2-hydroxy-6-bromo- or 2-hydroxy-6-chloropyridine derivative of formula VI with a compound of formula IV in a molar ratio of 1:1 in accordance with reaction: ##SPC8##

The reaction is carried out in a suitable solvent at temperatures of 20° to 100°C. The data respecting the solvents and the meaning and selection of Q set forth above for reaction equations (1) and (3), apply to reaction (4).

Compounds of formula VI may be prepared by the reaction of the corresponding 2,6-dihydroxypyridine compounds with phosphoroxychloride or phosphoroxybromide at 80-100°C. in an inert organic solvent such as benzene, toluene or xylene.

If reactions (1) through (4) are carried out at temperatures which are above the boiling point of a reaction constituent or of the solvent used, then the utilization of excess pressure is required.

For the preparation of the novel compounds of formula I, wherein the substituent Z₁ and/or Z₂ signifies a --SO₂ --R₁₂ radical, sulfinates are employed, preferably zinc sulfinates of the formula Zn (SO₂ --R₁₂)₂. They allow the introduction of, for example, the following radicals: methylsulfonyl, chloromethylsulfonyl, ethylsulfonyl, 2-chloroethylsulfonyl, n-propylsulfonyl, isopropylsulfonyl, n-butylsulfonyl, isobutylsulfonyl, sec.-butylsulfonyl, n-amylsulfonyl, isoamylsulfonyl, n-hexylsulfonyl, cyclohexysulfonyl, benzylsulfonyl, phenylsulfonyl, 2,4-dimethylphenylsulfonyl, 4-methylphenylsulfonyl, 4-methoxyphenylsulfonyl, 4-chlorophenylsulfonyl, 4-chloro-3 -methylphenylsulfonyl and 4-bromophenylsulfonyl.

The compounds of the present invention are valuable intermediates, in particular for the preparation of dyestuffs, preferably of azo dyestuffs. As far as these azo dyes do not contain ionogenic groups, they may be employed as disperse dyes for dyeing and printing synthetic hydrophobic fiber material, whereas those azo dyes which do contain ionogenic groups are suited for dyeing and printing cotton, wool, silk, polyamide and modified polyacrylonitrile.

Moreover, the compounds of the present invention are valuable pest control agents -- in particular if they are employed as insectizides --, as well as valuable pharmaceuticals -- above all if they are employed as analeptics, analgetics and diuretics.

Azo dyes containing the compounds of the present invention may be prepared, for instance, by diazotizing a diazotizable aromatic amine and coupling it with a compound of the present invention. The diazotization and the coupling are carried out in the usual manner. According to the respective initial products employed, this working method leads to the preparation, for instance, of disperse dyes, reactive dyes, cationic dyes or acid dyes. All of these azo dyes exhibit outstanding tinctorial properties, in particular a high coloring strength and a very good fastness to light, perspiration, water, sea water, alkalies and to washing. The disperse dyes distinguish themselves above all by an excellent fastness to dry-heat pleating and setting, ozone, waste-gas fading and to rubbing, by a high resistance when subjected to various permanent press treatments and by a good covering power even when applied onto textured polyester materials. The reactive dyes distinguish themselves in particular by an even color depth obtained in the different setting processes. The azo dyes mentioned hereinbefore are suited for dyeing and printing textile materials according to various known processes. The preparation of the dyes as well as their application for dyeing and printing are described in Examples 15-19.
